Love this exhaust! It is louder in the beginning then it tones down a bit. Beautiful rumble at idle. Vehicles behind me stay a distance. Guess they don't like the noise! Overall, I have no regrets on my purchase. Highly recommended for the car/truck enthusiast!

I was able to install the Cat-Back JBA system in less than 2 hrs. Very pleased with the instructions especially for a novice like myself. The ONLY drawback was the noise level is extremely LOUD for a family car. I did not see anywhere this is an aggressive system. I will probably look to change Mufflers in the near future!
